Running aem Intake and hps charge pipe what is the best power box to go with? Thanks if any one has any feedback.

E46CT

Honestly stock is best. a power box is just going to fry your cats prematurely due to excess egts if you use it long term. you'll be stuck with a high repair bill.

also the transmission logic control and hydraulic valve body pressures aren't really tuned/programmed for the added torque. you'll wear the clutch packs faster.

I agree with E46CT, Sport mode is more than enough for me. BUT, if you are really set on this, OrangeVirus is the best ECU tune I can find for the NX engine compared to all the piggyback tunes.

I like the BMS JB4. I have it on my GS200t and its easy to install. Get the bluetooth module so that you can easily datalog and monitor OBDII with your phone . I'll transfer it to our NX once my GS warranty is up and I can dive further into a custom tune and water injection.

I'd say Tom's Racing.. have one in stock. Its a simple piggy back for uninstall/install.
